Role of Frontier Molecular Orbital Symmetry of Reagents in Redox Catalytic Indicator Reactions

Journal of Analytical Chemistry, 2005
Some hypotheses are discussed for the nature of “inhibited” or “kinetically hindered” redox reactions, which are employed as indicator reactions in kinetic analytical methods. Some reactions are considered as examples to demonstrate that redox reactions are kinetically hindered because the key frontier orbitals of the reagents differ in their symmetry ...

A study of a reaction system for organic acid analysis using a pH indicator as post-column reagent

Journal of Chromatography A, 1984
Abstract A post-column reaction system using a pH indicator for organic acid analysis has been studied theoretically with the aid of computer calculation. This examination has revealed that bromothymol blue (BTB) is a most suitable pH indicator for this purpose.

Densities, Viscosities, and Refractive Indices of Aqueous Alkanolamine Solutions as Potential Carbon Dioxide Removal Reagents

Journal of Chemical & Engineering Data, 2012
To determine the possibility of improvement of the process of CO2 removal by absorption with alkanolamines, densities, viscosities, and refractive indices of four aqueous alkanolamine solutions (water + monoisopropanolamine (MIPA), diisopropanolamine (DIPA), triisopropanolamine (TIPA), or diethanolamine (DEA)) were measured in the temperature range ...

The case for the use of unrefined natural reagents in analytical chemistry—A green chemical perspective

, 2010
An important part of the Green Chemistry philosophy is the need to develop and adopt green analytical techniques and procedures. These include the reduction of reagent and solvent usage, the minimization of solid, liquid and gaseous materials produced by

Endothelium-Derived Extracellular Vesicles Expressing Intercellular Adhesion Molecules Reflect Endothelial Permeability and Sepsis Severity

Anesthesia and Analgesia
BACKGROUND: Currently, clinical indicators for evaluating endothelial permeability in sepsis are unavailable. Endothelium-derived extracellular vesicles (EDEVs) are emerging as biomarkers of endothelial injury. Platelet endothelial cell adhesion molecule

DEVELOPMENT OF AN INDICATOR DISPLACEMENT ASSAY REAGENT FOR SACCHARIDE QUANTITATION

2020
Boronic acid-appended molecules have been popular in classical guest-host interactions with saccharides that use an integrated indicator-receptor motif. Though the literature shows a number of novel sensors varying in degrees of synthetic difficulty and water solubility, such sensor systems were never refined into a working analytical tool. A promising
